| Abstract: | Based on the theory of safety related communication in open transmission systems,this paper analyzed the characteristics and strategies of open transmission systems and then discussed error control as well as prevention of unauthorized access methods of CTCS-3 safety data transmission over GSM-R in that aspects of data link layer and transport layer.A detailed process of establishing CTCS-3 safety connection over GSM-R open system is proposed through analysis. |
